Orbital Debris Removal by Laser Radiation.

Abstract

The use of high-power lasers is suggested for the removal of small orbital debris of up to 10 cm in diameter. Assuming data for a most probable collision orbit and for realistic ejection speeds of debris vapor under laser irradiation, calculations show the feasibility of tre ating a debris object like a laser-propelled rocket. The acceleration of the debris during irradiation allows to change its orbit for a direct reentry into the earth atmosphere. An autonomous orbital vehicle could eventually clear the whole low earth orbital environment from small debris. In a modification of this method a laser could be used on short note to divert the flight path of a piece of debris to avoid a collision.
